Exosomal Lnc-DLK1-35 reprograms microglia into a pro-tumorigenic phenotype via a non-canonical cytokine signature to promote glioblastoma progression and chemoresistance.

Abstract excerpt

INTRODUCTION: Temozolomide (TMZ) resistance in glioblastoma (GBM) involves dynamic crosstalk of cancer cells with tumor-associated microglia, but the role of exosomal long non-coding RNAs (lncRNAs) remains poorly defined. MATERIAL AND METHODS: We isolated exosomes from TMZ-sensitive (U251) and TMZ-resistant (U251TR) GBM cells. Lnc-DLK1-35 expression was modulated by overexpression/knockdown and validated by...
